To all `whom t 'may Canccggn.'

Be it known that We, JOHN'DMIES and WILLIAM llnxn violins, subjects of the King of (i1-ent. Britain, iesiding. respectively, in Liverpool. in the connty of `Lnncnsben und iifellnsey, in the county of Chester, in the liingiloui of England, have invented certain new and useful improvements in or Relating to the linnuffu-tux'e of Heat-Insnlating Chumbcrs, Wnlls, Floors, :intl Ceilings, of which the following if; n specification.

This invention relates-to a system for maliingr insulating surfaces, roonis and `the like.

All present insulation is largely mode of compi-concu cork. The pieces of cork unie togcthc hy the slight decomposition of the cork under henk, producing sufcient comen iiiousi maite?? io bind the Whole together.

Rooms sind .iloois have been repeuielly malle of more oilens iiiwous ninierinl coutefi over with cement, but our invention consists in forming;- nolid lilools of e tough organic motorini such -i n coinpzressed cork,`nnci forining on the surface of these squared blocks oi' plates or tiies, o, howl or smooth surince of cement, which iioni its own nature ntinches itself iiifmljy ifo the organic lnyezs. rliliese blocks nre then built up whether in n ioo', n ceiling or' in wills, june ns oshlei` masonry or brick muy he, only We prefer to use pre csely the sinne cement that forms the outer loyer or layer openV to the atmosphere.

Pari: of n. partition, Wall or ceiling, necorciinggl fo the proscrit invention, is illustrated in che drawing, in which a', is the part of the block formed of cork, while lb is the cement covering; or cootn for the sonnen The integrnl blocks formedpliy thc porfin a are set up in position and the intenstices nre illeil with n fronting of cement c which. pre/forcibly oi" siniiininninie to the poc tion. Y) of ille block.

The cement which We prefer to use ie ihe well limown. mixture of cnlcined inagnesiie, chlorid of niogneoinni und sawdust, oiother like fibrous ninierinl, the 'chloricl of'4 mng noeiuin anni mngncnin noting on cach other to form onychloriil of magnesium, whi'ievthc mwilunia, han" oioilier inntciinl that is 'mixed wiirh il;` nnilicsi ii. oxiiiemely tough., Tho
